Top Gear is a BAFTA, multi-NTA and Emmy Award-winning BBC television series about motor vehicles, mainly cars. It began in 1977 as a conventional motoring magazine show. Over time, and especially since a relaunch in 2002, it has developed a quirky, humorous style. The programme is estimated to have 385 million viewers worldwide and 11 million viewers each week, with one episode (Series 7 Episode 5) having 21 million viewers in the UK on BBC Two. The show is presented by Jeremy Clarkson, Richard Hammond, James May and The Stig, an anonymous test driver. In 2007 it was one of the most pirated television shows in the world.
